[Explanation of Embodiments of the present disclosure]
First, the embodiments of the present disclosure will be listed and described.

A waterproof member is provided so as to bridge between the first exterior member and the second exterior member. Therefore, the relative movable section of the electromagnetic wave absorbing member is limited to the inside of the waterproof member. As a result, it is possible to prevent the electromagnetic wave absorbing member from coming into contact with a liquid such as rainwater, so that it is possible to prevent the electromagnetic wave absorbing member from being rusted or the like. Further, since the first regulating member and the second regulating member are formed separately, the materials and shapes of the first regulating member and the second regulating member can be individually selected. This makes it possible to improve the degree of freedom in designing the wire harness.

Here, the "ring" in the present specification is a circular ring having a circular outer edge shape, an elliptical or oval ring having an outer edge shape, a polygonal ring having a polygonal outer edge shape, and a polygonal ring having a rounded outer edge shape. Including, the outer edge shape is composed of any closed shape connected by a straight line or a curved line.

The "ring" includes a ring having a predetermined length extending along the central axis direction in which the central axis passing through the center of the through hole extends, and the length thereof does not matter. Further, the “ring” in the present specification may be regarded as a ring as a whole, and includes a C-shaped one having a notch or the like in a part thereof.

[2] The electric wire and the tubular electromagnetic shield member that covers the outer periphery of the electromagnetic wave absorbing member are further provided, and the first exterior member and the second exterior member are provided so as to cover the outer periphery of the electromagnetic shield member. The waterproof member is preferably provided so as to cover the outer periphery of the electromagnetic shield member.

According to this configuration, the electromagnetic wave radiated from the electric wire can be reduced by the electromagnetic wave absorbing member and the electromagnetic wave shielding member covering the outer periphery of the electromagnetic wave absorbing member. Further, since the outer periphery of the electromagnetic shield member is covered by the first exterior member, the second exterior member, and the waterproof member, it is possible to prevent the electromagnetic shield member from coming into contact with a liquid such as rainwater.

[3] The first regulating member and the second regulating member are preferably formed so as to tighten the electromagnetic shield member toward the electric wire from the outside of the electromagnetic shield member.

According to this configuration, the electromagnetic shield member is tightened toward the electric wire by the first regulating member and the second regulating member. Therefore, it is possible to prevent the electromagnetic shield member from spreading outward in the radial direction of the electric wire. As a result, workability when attaching the waterproof member can be improved.

[4] The electromagnetic shield member has an electromagnetic shield member that covers the outer periphery of the electric wire, and the electromagnetic shield member penetrates the through hole while covering the outer circumference of the electric wire, and the first exterior member and the second exterior member. The member is preferably provided so as to cover the outer periphery of the electromagnetic shield member.

According to this configuration, the electromagnetic wave radiated from the electric wire can be reduced by the electromagnetic wave absorbing member and the electromagnetic wave shielding member penetrating through the through hole of the electromagnetic wave absorbing member. Further, since the electromagnetic shield member is made to penetrate through the through hole, it is possible to prevent the electromagnetic shield member from spreading outward in the radial direction of the electric wire. As a result, workability when attaching the waterproof member can be improved.

[5] It is preferable that at least one of the first regulating member and the second regulating member is a tape member.

According to this configuration, the tape member can prevent the electromagnetic wave absorbing member from being displaced in the length direction of the electric wire.

[6] At least one of the first regulating member and the second regulating member is a binding having a strip-shaped portion and a lock portion integrally formed with the strip-shaped portion at a base end portion in the length direction of the strip-shaped portion. It is a band, and the lock portion preferably faces the side surface of the electromagnetic wave absorbing member.

According to this configuration, the movement of the electromagnetic wave absorbing member in the length direction of the electric wire can be regulated by, for example, bringing the side surface of the electromagnetic wave absorbing member into contact with the lock portion of the binding band. Further, in the binding band, since the band-shaped portion can be easily wound around the outer circumference of the electric wire, the workability of assembling the wire harness can be improved.

Here, "opposing" in the present specification means that the faces or members are in front of each other, not only when they are completely in front of each other, but also when they are partially in front of each other. Including the case of being in position. Further, the term "opposing" in the present specification refers to both the case where a member other than the two parts is interposed between the two parts and the case where nothing is interposed between the two parts. including.

According to this configuration, the tip of the band-shaped portion is formed so as to protrude outward from the lock portion. Thereby, the outer peripheral dimensions of the first regulating member and the second regulating member can be formed large. Therefore, it is possible to preferably prevent the first regulating member and the second regulating member from being inserted into the through hole of the electromagnetic wave absorbing member. As a result, the movement of the electromagnetic wave absorbing member can be suitably regulated by the first regulating member and the second regulating member.

[8] The electromagnetic wave absorbing member includes a first end portion in the central axis direction in which the central axis of the through hole extends, a second end portion opposite to the first end portion in the central axis direction, and the first end portion.

The outer shape of the second end portion is formed so as to become smaller toward the direction of the second end portion, and the outer shape of the outer peripheral surface of the second end portion becomes smaller toward the end surface of the second end portion in the central axial direction. It is preferable that it is formed in such a manner.

According to this configuration, the corners of both ends of the electromagnetic wave absorbing member in the central axis direction are formed in a tapered shape. Therefore, even if the outer surface of the electromagnetic wave absorbing member comes into contact with the electromagnetic wave shielding member due to the vibration of the electromagnetic wave absorbing member due to the traveling of the vehicle or the like, the electromagnetic wave shielding member wears due to the contact. Can be suppressed. As a result, damage to the electromagnetic shield member can be suppressed.

[9] It is preferable that the covering member further covers the outer circumference of the electric wire, and the covering member penetrates the through hole while covering the outer circumference of the electric wire.

According to this configuration, the electric wire is penetrated through the through hole of the electromagnetic wave absorbing member while being covered with the covering member. Therefore, it is possible to prevent the inner peripheral surface of the through hole from directly contacting the outer peripheral surface of the electric wire. As a result, damage to the electric wire due to contact with the inner peripheral surface of the through hole can be suitably suppressed.

[10] The covering member is formed in a sheet shape having a slit extending along the length direction of the electric wire, and the covering member is a third end in a first direction intersecting the length direction of the electric wire. It has a portion, a third end portion, and a fourth end portion provided on the opposite side in the first direction, and the covering member overlaps the fourth end portion with the third end portion. As a result, it is formed so as to form a tubular shape that surrounds the outer periphery of the electric wire over the entire circumference in the circumferential direction, and at least one of the first regulating member and the second regulating member is circumferentially surrounding the outer periphery of the covering member. It is preferable that the cable is provided so as to surround the entire circumference.

According to this configuration, by superimposing the fourth end portion on the third end portion of the sheet-shaped covering member, the covering member can be formed into a tubular shape that surrounds the outer circumference of the electric wire over the entire circumference in the circumferential direction. .. Therefore, the covering member can be easily attached to the electric wire later. Thereby, the assembly workability of the wire harness can be improved.

Further, by forming the first regulating member or the second regulating member so as to surround the outer circumference of the covering member over the entire circumference in the circumferential direction, the tubular state of the covering member is maintained by the first regulating member or the second regulating member. be able to.

For example, in the length direction of the electric wire 20, a corrugated tube 40 is provided on one side of the electromagnetic wave absorbing member 70, and a corrugated tube 50 is provided on the other side of the electromagnetic wave absorbing member 70. The electromagnetic wave absorbing member 70 is provided, for example, apart from the corrugated tube 40 in the length direction of the electric wire 20. The electromagnetic wave absorbing member 70 is provided, for example, apart from the corrugated tube 50 in the length direction of the electric wire 20. The electromagnetic wave absorbing member 70 is exposed from, for example, the corrugated tubes 40 and 50.

The electromagnetic wave absorbing member 70 absorbs a part of the electromagnetic wave (electromagnetic noise) radiated from the electric wire 20, for example.

The electromagnetic wave absorbing member 70 has, for example, a through hole 71 through which a plurality of electric wires 20 collectively penetrate. The electromagnetic wave absorbing member 70 has an annular shape, for example, by having a through hole 71. The electromagnetic wave absorbing member 70 has, for example, a through hole 71 in a plan view seen from the length direction of the electric wire 20, and has a predetermined length extending along the central axis direction in which the central axis passing through the center of the through hole 71 extends.

The electromagnetic wave absorbing member 70 of this embodiment is composed of only an annular magnetic core 72. The magnetic core 72 of the present embodiment is formed in an annular shape. The magnetic core 72 has, for example, a function of reducing electromagnetic waves radiated from the electric wire 20 by being arranged so as to face the electric wire 20 over the entire circumference of the electric wire 20 in the circumferential direction. The magnetic core 72 absorbs electromagnetic waves radiated from, for example, the electric wire 20, and converts the energy of the electromagnetic waves into mechanical energy such as vibration or thermal energy. As a result, the adverse effect of the electromagnetic wave radiated from the electric wire 20 on the peripheral equipment and the like is reduced.

The magnetic core 72 is, for example, a molded product containing a soft magnetic material. Examples of the soft magnetic material include iron (Fe), iron alloy, ferrite and the like. Examples of the iron alloy include Fe-silicon (Si) alloy and Fe-nickel (Ni) alloy. As the magnetic core 72, for example, a ferrite core, an amorphous core, or a permalloy core can be used. The ferrite core is made of, for example, soft ferrite exhibiting soft magnetism. Examples of the soft ferrite include a ferrite containing nickel (Ni) and zinc (Zn) and a ferrite containing manganese (Mn) and zinc (Zn). The material of the magnetic core 72 can be appropriately selected, for example, according to the frequency band of the electromagnetic noise to be reduced.

As shown in FIG. 3, the magnetic core 72 of the present embodiment is continuously formed over the entire circumference in the circumferential direction, and is formed in a closed ring shape. That is, the magnetic core 72 of the present embodiment is formed in a structure in which the whole is connected to form a ring without a break, that is, an endless structure in which the start point and the end point coincide with each other. In other words, the magnetic core 72 of the present embodiment is not formed with a slit extending along the central axis direction. The magnetic core 72 of the present embodiment is composed of one component. In the present embodiment, the magnetic core 72 is composed of one component, but a plurality of core materials may be combined to form an annular magnetic core 72. For example, the magnetic core 72 may be formed in an annular shape by combining a pair of core materials having a semicircular cross section.

As shown in FIG. 2, the magnetic core 72 includes, for example, an end 73 of the magnetic core 72 in the central axis direction, an end 74 opposite to the end 73 in the central axis direction, and an end 73 and an end. It has a central portion 75 provided between the portion 74 and the portion 74.

It has a side surface 72C extending along the radial direction of the corrugated tube 50 and facing the corrugated tube 50 side. The side surface 72B constitutes an end surface of the end portion 73 in the central axis direction. The side surface 72C constitutes an end surface of the end portion 74 in the central axis direction. The side surfaces 72B and 72C are provided, for example, between the outer peripheral surface 72A and the inner peripheral surface of the through hole 71. The outer peripheral dimension of the magnetic core 72 is set to be larger than the outer peripheral dimension of the corrugated tubes 40 and 50, for example. Therefore, the outer peripheral surface 72A of the magnetic core 72 is provided at a position protruding outward in the radial direction from the outer peripheral surfaces of the corrugated tubes 40 and 50.

The end portion 73 of the magnetic core 72 is formed so that the outer shape becomes smaller, for example, from the central portion 75 side toward the side surface 72B which is the end surface of the end portion 73 in the central axial direction. The outer peripheral surface of the end portion 73 has, for example, a tapered portion 73A whose outer diameter decreases from the central portion 75 side toward the side surface 72B. The outer peripheral surface of the tapered portion 73A is formed so as to be inclined so as to approach the inner peripheral surface of the through hole 71 from the central portion 75 side toward the side surface 72B, for example. The tapered portion 73A is provided on, for example, at least a part of the outer peripheral surface of the end portion 73.

Although not shown, the tape member 101 has, for example, an overlapping winding structure. The tape member 101 has, for example, a half-wrap winding structure.

As shown in FIG. 2, the regulating member 100 does not surround the outer circumference of the electromagnetic wave absorbing member 70, for example. The regulation member 100 of the present embodiment does not cover the outer peripheral surface of the braided member 80 at the portion covering the outer peripheral surface 72A of the magnetic core 72. That is, the electromagnetic wave absorbing member 70 of the present embodiment is not fixed to the electric wire 20 by the regulating member 100. As described above, the electromagnetic wave absorbing member 70 of the present embodiment is not fixed to the electric wire 20 by the regulating members 90 and 100. The electromagnetic wave absorbing member 70 of the present embodiment is tightened radially inward by the braided members 80 which are tightened radially inward by the regulating members 90 and 100 provided on both sides of the electromagnetic wave absorbing member 70. As a result, the electromagnetic wave absorbing member 70 is fixed to the electric wire 20, and the relative movement of the electromagnetic wave absorbing member 70 with respect to the electric wire 20 is suppressed. That is, even when the electromagnetic wave absorbing member 70 itself is not fixed to the electric wire 20, the relative movement of the electromagnetic wave absorbing member 70 with respect to the electric wire 20 can be suppressed.

The wire harness 10 has a through hole 71 through which the electric wire 20 penetrates, covers the annular electromagnetic wave absorbing member 70 provided between the corrugated tube 40 and the corrugated tube 50, and the outer periphery of the electromagnetic wave absorbing member 70, and corrugates. It has a waterproof member 60 fixed so as to bridge between the outer periphery of the tube 40 and the outer periphery of the corrugated tube 50. The wire harness 10 is provided between the corrugated tube 40 and the electromagnetic wave absorbing member 70, and has a regulating member 90 that regulates the relative movement of the electromagnetic wave absorbing member 70 with respect to the electric wire 20 in the length direction of the electric wire 20. The wire harness 10 is provided between the corrugated tube 50 and the electromagnetic wave absorbing member 70, and has a regulating member 100 that regulates the relative movement of the electromagnetic wave absorbing member 70 with respect to the electric wire 20 in the length direction of the electric wire 20.

According to this configuration, regulating members 90 and 100 that regulate the relative movement of the electromagnetic wave absorbing member 70 with respect to the electric wire 20 are provided on both sides of the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20. These regulating members 90 and 100 can prevent the electromagnetic wave absorbing member 70 from being displaced in the length direction of the electric wire 20. Further, the electromagnetic wave absorbing member 70 is provided between the regulating member 90 and the regulating member 100, and the regulating members 90 and 100 are provided between the corrugated tube 40 and the corrugated tube 50. Then, a waterproof member 60 is provided so as to bridge between the corrugated tube 40 and the corrugated tube 50. Therefore, the relative movable section of the electromagnetic wave absorbing member 70 is limited to the inside of the waterproof member 60. As a result, it is possible to prevent the electromagnetic wave absorbing member 70 from coming into contact with a liquid such as rainwater, so that it is possible to prevent the electromagnetic wave absorbing member 70 from being rusted or the like.

(2) Since the regulation member 90 and the regulation member 100 are formed separately, the materials and shapes of the regulation members 90 and 100 can be individually selected. As a result, the degree of freedom in design of the wire harness 10 can be improved.

(3) Further, since the regulation member 90 and the regulation member 100 are formed separately, for example, the timing of attaching the regulation members 90 and 100 can be set to different timings. Thereby, for example, the regulation member 90 can be attached first, the regulation member 90 can be used as a positioning member to position the electromagnetic wave absorbing member 70, and then the regulation member 100 can be attached.

(4) The regulating members 90 and 100 are formed so as to tighten the braided member 80 toward the electric wire 20 from the outside of the braided member 80. According to this configuration, the braided member 80 is tightened toward the electric wire 20 by the regulating members 90 and 100. Therefore, it is possible to prevent the braided member 80 from spreading outward in the radial direction of the electric wire 20. As a result, workability when attaching the waterproof member 60 can be improved.

(5) Further, the braided member 80 is tightened toward the electric wire 20 on both sides of the electromagnetic wave absorbing member 70. Therefore, the braided member 80 that covers the outer circumference of the electromagnetic wave absorbing member 70 is also tightened toward the electric wire 20. The braided member 80 tightens the electromagnetic wave absorbing member 70 from the outside toward the electric wire 20. As a result, it is possible to preferably prevent the electromagnetic wave absorbing member 70 from being displaced in the length direction of the electric wire 20.

(6) Regulatory members 90 and 100 are composed of tape members 91 and 101. According to this configuration, the tape members 91 and 101 can prevent the electromagnetic wave absorbing member 70 from being displaced in the length direction of the electric wire 20. Further, since the tape members 91 and 101 are provided inside the waterproof member 60, it is possible to prevent the tape members 91 and 101 from coming into contact with a liquid such as rainwater. As a result, it is possible to preferably suppress the decrease in the adhesive force of the tape members 91 and 101 due to the contact with the liquid, so that the position regulation of the electromagnetic wave absorbing member 70 by the tape members 91 and 101 can be suitably maintained. ..

(7) The corners of the ends 73 and 74 in the central axis direction of the electromagnetic wave absorbing member 70 are formed in a tapered shape. Therefore, even if the outer surface of the electromagnetic wave absorbing member 70 and the braided member 80 come into contact with each other due to the vibration of the electromagnetic wave absorbing member 70 due to the traveling of the vehicle or the like, the braided member 80 is worn due to the contact. Can be suppressed. As a result, damage to the braided member 80 can be suppressed.

The covering member 110 is provided so as to surround the outer circumference of the electric wire 20 located between the corrugated tube 40 and the corrugated tube 50, for example. The covering member 110 is provided so as to surround the outer circumference of the electric wire 20 exposed from both the corrugated tubes 40 and 50, for example. The covering member 110 has, for example, a tubular shape that collectively surrounds the outer circumferences of the plurality of electric wires 20 as a whole. The covering member 110 is provided, for example, so as to surround the outer periphery of the plurality of electric wires 20 over the entire circumference in the circumferential direction. The covering member 110 is exposed from both the corrugated tubes 40 and 50, for example. The covering member 110 is provided so as to penetrate the through hole 71 of the electromagnetic wave absorbing member 70 in a state of surrounding the outer circumference of the electric wire 20, for example.

The outer peripheral dimension of the covering member 110 is set smaller than, for example, the inner peripheral dimension of the corrugated tubes 40 and 50. The covering member 110 may be accommodated in, for example, one end in the length direction in the internal space of the corrugated tube 40 and the other end in the length direction in the internal space of the corrugated tube 50.

As shown in FIG. 7, the covering member 110 is formed in a sheet shape having, for example, a slit 111 extending along the length direction of the electric wire 20. The covering member 110 is formed so as to form a tubular shape by, for example, winding a flexible resin sheet in the circumferential direction.

The inner peripheral dimension of the covering member 110 can be adjusted to match the outer peripheral dimension of the plurality of electric wires 20 by adjusting the overlapping width of the end portion 112 and the end portion 113, for example. The covering member 110 has elasticity capable of returning from a tubular state capable of surrounding the outer circumference of the electric wire 20 to a sheet state not surrounding the outer circumference of the electric wire 20, for example.

As the material of the covering member 110, a resin material having no conductivity is used. As the resin material, for example, synthetic resins such as polyethylene terephthalate, polyolefin, polyamide, polyester, and ABS resin can be used.

Therefore, it is possible to prevent the inner peripheral surface of the through hole 71 from directly contacting the outer peripheral surface of the electric wire 20. As a result, damage to the electric wire 20 due to contact with the inner peripheral surface of the through hole 71 can be suitably suppressed.

Further, by superimposing the end portion 113 on the end portion 112 of the sheet-shaped covering member 110, the covering member 110 is formed so as to form a tubular shape that surrounds the outer circumference of the electric wire 20 over the entire circumference in the circumferential direction. Therefore, the covering member 110 can be easily attached to the electric wire 20 later. Thereby, the assembling workability of the wire harness 10 can be improved.

-In the above embodiment, the regulation member 90 is embodied in the tape member 91, and the regulation member 100 is embodied in the tape member 101, but the present invention is not limited to this. For example, the regulating members 90 and 100 may be configured by a binding band made of synthetic resin or metal, a caulking ring or a clamp.

In the example shown in FIG. 6, the regulating member 90 is composed of a binding band 92 made of synthetic resin, and the regulating member 100 is composed of a binding band 102 made of synthetic resin. The binding bands 92 and 102 are provided so as to surround the outer periphery of the plurality of electric wires 20, for example. The binding bands 92 and 102 are provided on the outer periphery of the covering member 110 that collectively covers the plurality of electric wires 20, for example. The binding bands 92 and 102 are provided so as to surround the outer circumference of the covering member 110 over the entire circumference in the circumferential direction, for example. The binding bands 92 and 102 are provided so as to tighten the outer periphery of the covering member 110 inward in the radial direction, for example. The binding bands 92 and 102 of this modification have a function of maintaining the sheet-shaped covering member 110 in a tubular state, that is, a function of suppressing the covering member 110 from returning to the sheet state. The binding band 92 is provided between the corrugated tube 40 and the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20. The binding band 102 is provided between the corrugated tube 50 and the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20.

As shown in FIG. 7, the binding bands 92 and 102 have a long strip-shaped portion 93 and a lock portion 94 formed integrally with the strip-shaped portion 93 at the base end portion of the strip-shaped portion 93 in the length direction. ing. As the material of the binding bands 92 and 102, for example, polypropylene, polyetheretherketone, fluororesin, or the like can be used.

The lock portion 94 is formed so as to project outward from the outer peripheral surface of the strip-shaped portion 93, for example. The lock portion 94 is formed so as to project radially outward from the outer peripheral surface of the strip-shaped portion 93, for example. The lock portion 94 is formed in a rectangular parallelepiped shape, for example. The lock portion 94 has, for example, an insertion port 95 into which the strip-shaped portion 93 can be inserted. For example, a locking claw (not shown) is provided on the inner surface of the insertion port 95. On the outer peripheral surface of the tip portion 93A in the length direction of the strip-shaped portion 93, for example, a plurality of locking grooves (not shown) extending along the width direction of the strip-shaped portion 93 are spaced apart from each other in the length direction of the strip-shaped portion 93. It is formed with a space. In the binding bands 92 and 102 of the present embodiment, the locking claw of the locking portion 94 is engaged with the locking groove of one of the plurality of locking grooves formed in the band-shaped portion 93, whereby the locking portion 94 is engaged. On the other hand, the band-shaped portion 93 is locked. In the binding bands 92 and 102, for example, the degree of tightening of the covering member 110 by the band-shaped portion 93 can be adjusted according to the degree of insertion of the strip-shaped portion 93 into the lock portion 94.

The band-shaped portion 93 is wound around the outer side of the covering member 110 over the entire circumference in the circumferential direction of the covering member 110 with its tip portion 93A inserted into the insertion port 95 of the lock portion 94. The strip-shaped portion 93 is wound so as to come into contact with the outer peripheral surface of the covering member 110, for example. At this time, the tip portion 93A of the strip-shaped portion 93 projects outward from the lock portion 94. The tip portion 93A of the strip-shaped portion 93 protrudes outward in the radial direction from the lock portion 94, for example.

The binding bands 92 and 102 are formed in a size that cannot be inserted into the through hole 71 of the electromagnetic wave absorbing member 70. For example, the binding bands 92 and 102 are formed so that the lock portion 94 cannot be inserted into the through hole 71. The lock portion 94 of the binding band 92 is provided, for example, so as to face the side surface 72B of the magnetic core 72. The lock portion 94 of the binding band 92 may be brought into contact with the side surface 72B of the magnetic core 72, for example. The tip portion 93A protruding outward from the lock portion 94 of the binding band 92 is provided, for example, so as to face the side surface 72B of the magnetic core 72.

The tip portion 93A protruding outward from the lock portion 94 of the binding band 102 is provided, for example, so as to face the side surface 72C of the magnetic core 72.

According to the configuration described above, the binding bands 92 and 102 are provided on both sides of the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20. Since the binding bands 92 and 102 can regulate the movement of the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20, it is possible to prevent the electromagnetic wave absorbing member 70 from being displaced in the length direction of the electric wire 20. Further, the binding bands 92 and 102 are formed so as to cover the outer circumference of the covering member 110 over the entire circumference in the circumferential direction. As a result, the binding bands 92 and 102 can maintain the tubular state of the covering member 110. Therefore, the increase in the number of parts can be suppressed as compared with the case where the member that regulates the movement of the electromagnetic wave absorbing member 70 and the member that maintains the tubular state of the covering member 110 are separately provided.

Further, the regulating members 90 and 100 are composed of binding bands 92 and 102 having a band-shaped portion 93 and a locking portion 94, respectively. According to this configuration, the movement of the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20 can be regulated by bringing the side surfaces 72B and 72C of the electromagnetic wave absorbing member 70 into contact with the lock portion 94 of the binding bands 92 and 102. .. Further, in the binding bands 92 and 102, the band-shaped portion 93 can be easily wound around the outer circumference of the electric wire 20, so that the assembly workability of the wire harness 10 can be improved.

Further, the tip portion 93A in the length direction of the strip-shaped portion 93 is formed so as to project outward from the lock portion 94. The tip 93A of the binding bands 92 and 102 is formed so as to face the side surfaces 72B and 72C of the electromagnetic wave absorbing member 70. According to this configuration, since the tip portion 93A of the strip-shaped portion 93 is formed so as to project outward from the lock portion 94, the outer peripheral dimensions of the regulating members 90 and 100 can be formed large. Therefore, it is possible to preferably suppress the insertion of the regulating members 90 and 100 into the through hole 71 of the electromagnetic wave absorbing member 70. As a result, the movement of the electromagnetic wave absorbing member 70 can be suitably regulated by the regulating members 90 and 100.

Further, the regulating member 100 may be embodied as a tape member 101 that covers the outer circumference of the covering member 110 over the entire circumference in the circumferential direction. Even with this configuration, the tubular state of the covering member 110 can be maintained by the tape members 91 and 101. As a result, it is possible to suppress an increase in the number of parts as compared with the case where the member that regulates the movement of the electromagnetic wave absorbing member 70 and the member that maintains the tubular state of the covering member 110 are separately provided. In this case, the tape members 91 and 101 are wound on the outer peripheral surface of the covering member 110 so as to have a thickness that cannot be inserted into the through hole 71 of the electromagnetic wave absorbing member 70.

In the modified examples shown in FIGS. 6 and 7, the covering member 110 is embodied in a structure having a slit 111 extending along the length direction of the electric wire 20, but the present invention is not limited to this.

The covering member 110 is not particularly limited as long as it is an exterior member capable of covering the outer circumference of the electric wire 20, and may be formed of, for example, a corrugated tube. The corrugated tube in this case may have a slit extending along the length direction of the electric wire 20, or may not have a slit. Further, the covering member 110 may be, for example, a tape member. The tape member in this case is wound around, for example, the outer peripheral surface of the electric wire 20.

The binding bands 92 and 102 in this case are provided, for example, so as to tighten the braided member 80 from the outside of the braided member 80 toward the electric wire 20.

-The regulatory members 90 and 100 of the above embodiment may be embodied in different types of regulatory members. For example, the regulating member 90 may be embodied in the tape member 91, and the regulating member 100 may be embodied in the binding band 102. For example, the regulating member 90 may be embodied in a metal binding band, and the regulating member 100 may be embodied in a synthetic resin binding band 102.

-In the above embodiment, the regulating members 90 and 100 are provided at positions separated from the electromagnetic wave absorbing member 70 in the length direction of the electric wire 20, but the present invention is not limited to this. For example, the regulating members 90 and 100 may be formed so as to surround a part of the outer circumference of the electromagnetic wave absorbing member 70.

-In the above embodiment, the braided member 80 is provided so as to cover the outer periphery of the electromagnetic wave absorbing member 70, but the present invention is not limited to this.

For example, as shown in FIG. 9, the braided member 80 may be passed through the through hole 71 of the electromagnetic wave absorbing member 70. In this case, the braided member 80 is provided so as to penetrate the through hole 71 while surrounding the outer circumference of the electric wire 20, for example. The braided member 80 is provided so as to penetrate the through hole 71 in a state where the outer circumferences of the plurality of electric wires 20 are collectively surrounded, for example.

According to this configuration, since the braided member 80 is penetrated through the through hole 71, it is possible to prevent the braided member 80 from spreading outward in the radial direction of the electric wire 20. As a result, workability when attaching the waterproof member 60 can be improved.
